McKinley, committed to California out of high school before failing to qualify academically, is becoming one of the most sought after recruits in the nation.
His list has grown over 15 scholarship offers, but as February's National Signing Day inches closer, McKinley is already zeroing in his favorites list.
But don't get confused, McKinley tells Scout that although he knows four visits for sure, that doesn't mean those programs are necessarily ahead of the next three.
"They are pretty much even," McKinley told Scout. "Once I take my visits, that's when I'll know which schools I'm comfortable with, which staffs I'm comfortable with – what's the right fit."
McKinley continued to work on figuring out the fit on Wednesday.
He made the flight down from Northern California to spend the morning at USC, where he clocked his 4.45 40-yard dash. It was his firs time on the Trojans campus.
"I just went on a little tour, met the coaches as well, and that's pretty much it," McKinley said of his time at USC.
He's not sure if the visit to Troy tipped the scale enough to give the Trojans his fifth official visit.
"I don't know," McKinley explained. "I've been stuck on this for a month. That's why I came down here today, to check out USC to see how, if I like it, or how I feel in LA. To see the coaches, how they coach – just to see how it is.
"But, I still don't know. They did a pretty good job. I just need to go back and talk to parent/guardian and see what he thinks."
The visit to USC didn't last long; his flight back to Northern California was set for 8:35pm and he had one more stop he wanted to make after working out at USC.
"I thought, ‘Man, since I'm done here I should go over to UCLA and see the coaches and surprise them'."
McKinley spent time at the Bruin Elite Camp visiting with his recruiters, defensive coordinator Jeff Ulbrich and defensive line coach Jeff Ulbrich.
"[Our relationship] is real good, it is real good," McKinley explained, "Because I went to high school with [UCLA receiver] Kenneth Walker, so they already knew about me. They were like we have a guy that's only a junior and he played behind Kenny or whatever, so he came down to see me – but at the time I was already committed to California and stuff like that.
"But he says once he found out I was a non-qualifier he was excited to know that they have a chance to get me again so we have been having a tight relationship."
